The battery life while in use is amazing. The battery life while closed and apparently asleep is abysmal and probably the worst of any laptop I’ve used in the last 20 years.

I think the problem is that Safari allows tabs to ask to be periodically woken while the laptop is asleep, and there is no obvious way to turn this off. And it will keep doing this until the battery is so low that the laptop needs to hibernate.

Safari on Desktop is just appalling, every year you wish there are some improvements and it is the same. webkit gets some update in terms of web features and bug fix. Safari itself doesn't seems to want to improve. Even Orion using same webkit engine is better.

TL;DR: Make sure Power Nap is turned ON. It allows macOS to consolidate wakeup requests into a bulk queue. So the thing isn't turning on all the time.

I read that. It contains no actual useful or authoritative explanation. It references Apple docs that sort of say that it's not supported on Apple Silicon. The man page says:

> powernap - enable/disable Power Nap on supported machines (value = 0/1)

Thanks, Apple.

Use Chrome. Problem solved.
